My Craftsman lawnmower has a Briggs & Stratton Platinum Series 725 engine.
The engine just will not start. I began troubleshooting with my regular yearly maintenance:
1. Removed any old gas from previous season
2. Remove oil from previous season
3. Changed spark plug
4. Sprayed carb cleaner into carburetor
5. Replaced air filter
6. Added new oil
7. Added new gas
My lawn is so small that my mower only gets used for 3 or 4 hours total in a season. Some would say that it's overkill for me to replace the oil, filter, and plug each season.
Tried it out, it ran for about a half of a second before shutting off. So then I tried the following:
1. Removed fuel line and flushed it out
2. Cleaned out fuel tank
3. Removed carburetor and cleaned it out thoroughly
Tried it again, it did the same thing, ran for about a second then quit. So I tried to run it again, this time it didn't start at all.
I had hunch that it was just starting, and burning off the carb cleaner then stopping. So I sprayed a little into the carburetor and tried it again. Again it ran for a second and then stopped. After a bit of playing around with it, I discovered that I could spray some carb cleaner into the carburetor, start it, then immediately start spraying more into the carburetor and it would continue to run. So it runs off the carb cleaner, but for some reason it's not running off of the gas.
I don't know what's causing the problem or what I should do next, my knowledge of small engines is pretty limited.
Any help would be appreciated.
Thanks,
Matt
